Actually the incredibly low frequency response of most transducers is
preferred for home theater. You don't want your couch vibrating from
every noise in the movie, just things like explosions. People said
that if they felt vibrations from people talking it got annoying after
a while, so the low frequency response solves that problem. Of course
with sim racing I want all the screaming highs of the motor shaking my
chair and pedals so something with a much larger frequency response is
needed.

I was thinking that it will do the trick, But I also can imagine I'll
have to crank the volume up too much.

I did take my surround sound system with a good (un-powered) subwoofer
and put that behind the seat and it did the job but I had to bring the
volume up a bit more then I wanted to. I'm thinking of bringing this new
***pit to LAN events, so I'll need something like what was mentioned here
earlier (http://www.racesimcentral.net/). As Stated, $225.00 is a bit
pricy. I'd grab it if someone here had one and could tell me how good it
was :-)

Just got done reading all the other idea's in this thread. WOW, lots of
good stuff out there! I'll be putting a lot of gizmo's in the***pit but
this is the biggy that needs to be figured out.

BTW: If I didn't mention this before, The***pit (hopefully) will be
going to LAN events. Odds are that if everything gets in the***pit that I
want in it, When I do go to a LAN event, I'll probably need a portable
nuclear power station to run the thing ;-)

Just wondering, where in the world do you find LANs where anyone actually
wants to play racing games??? All I can get around here is RTCW, MOH, CS,
and all of that...I'd love to get a racing game going on a LAN sometime,
even if it is just a Need For Speed game. I played many a NFS3 game on my
home network back in the day; those were a blast!!!

DAMN IT! Someone set up a LAN event
in or near the FingerLakes region of NY

This would be the biggest help to me in building my***pit.

(Thanks Milhouse, perfect intro. to what I wanted to say;-)

They had an awesome setup last year, I was fortunate enough to be able
to attend the Baltimore LAN as their guest on my vacation last year, 80
something guys in one huge conference room racing in 3 divisions with
officials monitoring the whole event

Some guys were flying in from pretty far away, Shawn Wise from Papy was
one of the guys attending, not as a papy employee, but as a racer

Good weekend that :-)

Beers and cheers

Get a sub-woofer, and crank her up. It WILL shake, belive me (try attaching
it to the bodywork.) Is it just a rumble (like at a race start in GPL) or
full tilting?

In the same vein, on a lark I picked up a couple of Aura Interactor
backpack type devices at a show. I cut off the straps, bungee corded
the thing under my chair (recliner) against the metal wires that run
under there, and ran UT. It shook me so hard that my vision blurred.
I have to run it on volume 3. It gives a great effect over rumble
strips, and I'd venture to say that another in the back would work
well. You may be able to find these fairly cheaply (I bought mine for
$5 each). A quick search revealed this:

I saw a website for a company that made just that thing, a chair or
cushions for a chair that mechanically vibrate rather than using sound.
Don't recall where it was, but probably a link on one of the expensive
commercial game***pit sites.

Gavel....

RBH no longer makes those units, or the amp they originally sold for them.
I have not found a replacement as of yet. The transducers you speak of do
not work very well. At least, I've not been able to make the ones I tried
out.... work very well (I'm not an audiophile). They respond to frequencies
that are too low for engine sounds....so the "frequency" of the vibration
you feel is not "tight" enough to match what a V8 engine vibration feels
like. Its hard to describe in words, but maybe you know what I mean?

I agree with you...I was surprised the amp sold with the RBH actuators
(their term, not mine) was overheating and kicking in the protection
circuits. It only does it when the cross over is turned off...the amp set a

center-rear feed from a Dolby 6.1...with the surround sound amp "cranked."
That combo produces a 95% accurate engine vibration. I used to turn it
down....live with something "less".....but I tried removing the amp cover,
attaching a 120mm case fan (running off the computer power supply)....and
now the thing runs for ever without kicking out from the protection
circuitry. Maybe someday the whole thing will blow up? .....lol....

I wonder if the transducers you talk about would work better if they were
sent a noise signal from the center rear? Can you increase somehow, the
frequency they respond to? I wonder? The only units I've found that claim
to do what these RBH units do......were $1,500....and since mine work (for
now), I wasn't inclined to experiment with them. I will try to find the
link for them.....so you can at least take a look at the
details/specs....see what you think about them. If I find it, I'll post it
here.

The "rig" that I posted a picture of (which no longer exists...I now have an
enclosed***pit with a roof) also uses a PA speaker system (18" Fender L/R
mains and an 18" Peavey center). I use 6" commercial outdoor speakers for
the rears...mounted within a couple inches of my head - L/R. If I crank
this system....I get 120-130 db's in the***pit (I use ear plugs...but
that's perfect for recreating the sound environment of the real cars I've
driven) along with a racing helmet with headphones built into the
helmet.....that is separately amp'd and eq'd......to filter out all sound
but the high's.....it works perfect to semi-isolate the spotter's radio
calls...and it sounds like the "Racing Radio" system I used in my GT3
racecar). But, running this system "cranked"....vibrates stuff off the
shelves and tilts all the pictures in the entire house. It also manages to
get the cops out to my house quite regularly....and I live on 5 acres out in
the country! .....lol... Fortunately, the cops like racing so I let them
drive for a while (turned down)...they bury an incident report.....tell my
neighbors that "he's legal.....but we did get him to turn it down"....its
way too funny! Neither one of my neighbors who call the cops....have caught
on to this yet. -:)

Sounds like we have very similar sound systems.....like it loud and real!
That's cool.

Regards,

Tom

Sounds like the transducers are being overloaded; strange if that's the
amp shipping with the units. Split em and just do a stereo or mono feed to
them and see if it makes a difference. The things are only reproducing the
bottom anyhow.
I've never been inside of a race car so I haven't a clue how it's
supposed to sound. But the shakers lend themselves to the suspension of
disbelief for me. There was a fella a few years back who built a chair
using pneumatic actuators and microswitches to tilt his seat forward and
back with accel and braking inputs. Interesting idea . Vibration is okay but
seat movement in concert with the sim would top the cake.
I remember as a kid going to Disneyland and sitting in this mini-theater
where they pretended you were going on a ride into outer space. On liftoff
the seats lowered a little bit to simulate the G force. It doesn't take a
lot of movement to fool the body into thinking it's feeling something
powerful. And this technology was there in the sixties when I visited the
place. So I'm waiting for the FF wheel companies to install a pass thru
like a midi thru) that will allow us to plug in a chair loaded with small
actuators or bladders that respond to the same output the wheel receives.
Then, pressure sensitive switches to mount to our gas and brake pedals that
will trigger a five point harness tightening or a seat lowering to simulate
a g-force; nothing requiring massive movement, and finally a sound system to
rock your socks off.
I own a bunch of p.a. gear as I played in bands for years. I really don't
use it to race but I crank it up every now and then.
